He asked countries to bring announcements on climate action to a special summit of world leaders in New York next September.

Warning that people around the world now "face and fear the wrath of a warming climate," Ban urged delegates in Warsaw to think about their legacy: "Plan not only for your country, but for your neighbor and your neighbor's neighbor."
